To all 'whom it may concern.'

Be 'it known that I, FREDERICK W. RUTZKE, a su'bjectoi. theEinperor ot'Germany, and now residing in VVellston, county of St. Louis, and State of Missouri, have invented a new and useful Improvement in Window-Shade Fixtures, of whichfthe following is a specification. o

My' invention'relates to.. window shade fixtures oi ,the type in which thel shade roller is mounted-so Vthat it may be bodilyraised and lowered.

The principal objects of my invention are to provide a simple and eilicient construetion for Jfacilitating the bodily adjustment of the roller 4of a window shade which is durable and reliable; and to attain `certain advantages as, willmore fully appear hereinafter.

"The invention consists in theparts, and the arrangementsand Ecombinations of parts as will be more fully set forth hereinafter'. In the accompanying drawings, which `form partof the speciication, andv in which like reference characters refer to like part-s throughout the` different views,lFigure 1 is a front elevation of a construction embodying my invention, showingk it applied to a window of the ordinary form; Fig. 2 isa vertical section Aon the line 2-2 of Fig.4 1; Fig. is an enlarged side elevation of one endof a shade roller showing part of the invention applied thereto 5 Fig. 1 is "a vertical section on the line 4-4 on Fig.

3; Fig. 5 is avertical section on they line 5-5 Von Fig. 6; Fig. 6 is an enlarged side View of the fend of a shade roller opposite to the end shown in Fig.r3, the end of ythe roller being shown in section; Fig. 7 is a horizontal section on the line 7- -7 on Fig. 5; Fig. 8 is ahorizontal section on the line S-S on Fig. 5; Fig. 9 isa horizontal section on the line'9-9 onFig. 5; Fig.'10 is a side elevation of the cordf fastener; Fig.'11 isa vertical section on the line 11-11`on Fig. 10;.Fig. 12 is va horizontalsection on the line 12-12 on Fig. 1Q; Fig.' 13 is a detail of a headfon vone of the brackets.

A Adevice embodying the invention is capable of being attached to various 'forms of window frames and casings and oflbeing used with various types Joivshade rollers;

whilethe're is shown in the drawings a commonfo'rm fot' window frame andfcasing and shade roller,"`it 'is to' bexiiderstood that kSpecification of Letters Patent. Y* Patentd A1103 10, 1915. Application meer February 2, 1914. serial No. 815,962,

end to form a flangel or rimV 4. The other end of the roller l is lprovided with, the

usual pawl and ratchet spring controlling mechanism connected to an extending studL 5. AThe `stud 5 isrectangular in cross-secl'tion and has a notch' 6 infone of itsy edges.

` Arranged on the sides` of the window, preferably on the inside aceof the window casing upon the window stop?, are "guides 8 and 9. These guides 8 and 9 arethesame,

and a ldescription of one will sutiic'e for both.l The guide 8 is made of a `single strip of metal bent tok form a base' portion 10 which is securedV to the face of the *window stop 7 near the bottom and top thereof by screws 11. At one side margin bf the base portion 10 is a lateral guide flange 12 extending at right angles to said base portion. At the other side margin of the base portion 10 thestrip of metal is bent to `form an outer guide flange y18 whichis spaced from the base portion and has its marginal edge reinforced by a sharp rebend Q14, spaced from the lateral guide iange 12. The base portion 10, the lateral guide fiange`12 and the outer guide iange 13 torna` a 'guideway substantially L-shape in crossfsection. The guides' 8 and 9 extend from a point about half way up the window tothe topof lbody or' thebracket and thence parallel to the bracket to form a substantially L` 's hape 'Bange 16 which fits intov the vL-`shape guideway or the guide 8. 1n 'the u per part of the bracket 15 is a round hole 1 'at one `side of theV L-shapeflange 1 6, and onthe other side of said flange is a Adished head v18 which is a slot 19 extending Vupwardlyl and having a rounded bottom. Thefslot 119 is arranged to receive the exposed end the vpin 8, the rirngfl of said'pin engaging the concave side of the dished l'portion ofthe lhead 18, asshown to the best advantagein Fig. 6. f Y

' ,In the otherV guide la bracket 20 Vhav-l i ing an L-shape flange 21 fitted into the Y same manner a proper manipulation.

Leading from this rectangular opening 23- tothe edge of thel head 22 in a directioninclined to the vertical is a slot 24. A hook 25A is pivoted to the bracket 2O adjacent tov theY head 22 by anl integral finger 26 passed through a circular hole.27l in saidV bracket and bent back againstthe face of the head 20, asshown in Figs. 4 and 13- The hook 25 -lieson the concave side of the dished vhead 22, .and in its operative position, lies over the end of the slot 24 and yprevents the Y stud 5 from fbeing lifted outfof. said slot. Thefbracket 20 is provided with va circular hole 28.

The brackets l5 and 20 hold'the roller 1 in position so that itvcannot be accidentally displaced from the brackets; but at the same time the roller 1 may be Veasily removed by To remove the Y roller 1, the hook 25 is swung back to leave a free passage through the slot 24. The

vstud 5 is turned and lifted out ofthe slot 24. The bracket 15 is lowered luntil the rollerl 1 can be tilted so that the rim 4 on the pin 3k can followV the curvature ofthe dished. portion of the head 18.y Vhen the roller 1 is tilted in the proper manner, the pin 3 may be lifted out of the slot 19. The notch 6 inthe Vstud 5 prevents the stud being pulled endwise from the bracket 20. The rim 4 on the pin 3 likewise holds the pin from pulling endwise out of the bracket 15. A Vvertical movement of the stud 5 is prevented by the hook 25, and vertical movement of the pin 3 is prevented by the engagement of the rim 4 with the dished portion of the head 18. v

Y Knotted in the hole 28 in the bracket 20 is a cord 29, or oth-er flexible member, which extends upward over a guide member 30 fastened tothe head window stop 31, thence across the top ofthe window and over a second guide member 32, down the side of the windowk to a clip 33. Knotted in the hole 17 in the bracket 15 is another cordv 34 which extends upward over the guide member 32 and thence down to the clip 33, which secures to it the end of the cord 29. The cord 34 extends down along the side of the window to anyconvenient point, where it passes through'a fastening device.

. The `device for. fastening the cord 34 comprises a flanged cover plate 35 secured to the window stop. 7 by a screw 36, and between this cover' plate 35 and the face of the window stop is disposed a wheel 37,

mounted for free rotation upon a screw 38. Y rlhe wheel37 isuformed with a concave circular groove 39 near one end, and has a plurality, of concave grooves 40 extending from the circula-r groove 39 diagonally to the other end of the wheel. In the lower flange of thecover plate 35 is a pointed notch 41.v 'A ,Y

v In the operation of the window shade fixture which-I havey showngand described, the'cord 34 is loosened by pulling upon its free end. of the pointednotch 41, and the wheel 37 is partially rotated to bring the cord 34 into the circular groove 39. The shade rollerl '1 may now be bodily raised lor lowered by a proper manipulation of the cord 34. As the cords 34 and 29, which'are connected tothe The V`cord is thereby drawn out Y brackets 15 and 20 at the ends of the roller 1, are firmly secured ltogether by the clip 33, it is certain that both ends of the roller' 1 will be raised and lowered evenly. When the roller Vl has been adjusted to the desired position, tliecord34is released. The weight f of the roller l1 gives the wheel 37 part .of a revolutionin a reverse direction, and one of the' diagonal grooves' 40 engages the cord 34 and guides it to the outside of the wheel l 37 where itis clamped against the bottom fiange of the flanged coverplate 35. The pointed notch 41 forms an additional securing means for the cord 34.

Sometimes it happens that the width of n. the window varies slightly from the top to apart, a slight clearance is allowed between the L-shape flanges 16 and 21 of the brackets 15 and 2O and the Lshape guideways of the guides 8 and 9. 7|The screws 11 act as stops to limit the movement of the brackets 8 and 9 in their upper and lower positions. In the 'upper position, the rolll of the shade upon the roller 1 is close to tl a under face ofthe top window stop 31 so as to prevent the'un- 'winding' of the shade. Theparts are made of sheet metal and may be easily and cheaply stamped and bent to theV necessary shape.

Obviously, the construction I have shown and vdescribed is capablev of considerable modication withoutl departing from myinvention. Therefore, I do not wish to be limi ited to the exact construction which vI have shown and described. f
